Question

4x+9-y(6x+7)Select ALL the correct answers.Observe the expression below and select the true statement(s).The "7" in the third term is a coefficient.The "y" in the third term is a factor.The "6" in the third term is a coefficient.The "x" in the first term is an exponent.The "4" in the first term is a constant.The "9" in the second term is a constant.

Answer 1

- The expression given is:

`4x+9-y\left(6x+7\right)`

- A coefficient is simply a number that multiplies a variable term. For example in 5x, 5 is a coefficient, while x is the variable.

- A factor is a term or value that is multiplied with another term or number to form a composite term. Again, in 5x, 5 and x are factors of 5x.

- An exponent is simply the number with which another number or expression is raised.

- A constant is simply a number on its own.

- With the above definitions, we can proceed to solve the question.

- 7 is standing on its own, thus, it is a constant. This means that Option 1 is WRONG.

- y multiplies the bracket of 6x + 7. This makes y a factor. Option 2 is CORRECT.

- 6 multiplies x. This makes it the coefficient of x. Option 3 is CORRECT.

- x is multiplied by 4. This makes it a factor. Option 4 is WRONG.

- 9 stands alone. This makes it a constant. Option 5 is CORRECT
